CVE-2024-51978 Scanner

Brother Printers are widely used for various printing tasks in offices and homes across the globe. These devices are employed by businesses for efficient document printing and scanning processes. They are popular due to their reliability, speed, and cost-effectiveness. Additionally, Brother Printers are integrated into various network environments for centralized printing solutions. Their use extends to both personal and professional realms, making them an essential part of many operational workflows. These printers are available in multiple models, each offering unique features catering to different printing needs.

Default Credentials vulnerabilities are security lapses that occur when a product is shipped with a set of generic default login credentials. In the case of Brother Printers, such default credentials could be exploited by attackers to gain unauthorized access to the device. This type of vulnerability is critical because it requires no prior knowledge or access permissions for exploitation. The existence of default passwords significantly eases an attacker's ability to control or manipulate devices. If not remediated, this vulnerability could be leveraged to conduct data breaches or disrupt services.

The vulnerability involves the ability for a remote attacker to obtain a device's serial number via unauthenticated requests, which can then be used to calculate the default administrator password for Brother Printers. The template utilizes HTTP requests to extract potential serial numbers and other relevant data. By successfully acquiring the default administrator password, attackers can gain administrative access. This process relies on the exploitation of weak authentication mechanisms present within the printer's setup. The ability to bypass authentication using default settings poses a severe security risk.

Exploitation of this vulnerability could lead to unauthorized access and control over Brother Printers. Attackers gaining administrative access might alter device configurations, redirect print jobs, or access confidential documents processed by the printer. Additionally, compromised printers could be used as a pivot point for attacking other devices on the network. Furthermore, sensitive information stored or logged by the printer, including documents and credentials, could be exposed. The impact on organizational operations can be severe, potentially leading to data breaches and availability issues.
